About calories and electronvolts
Calorie (cal)
A calorie (cal) here is the thermochemical calorie, exactly 4.184 joules. Food "Calories" are kilocalories, a thousand times larger.
Electronvolt (eV)
An electronvolt (eV) is about 1.602 × 10⁻¹⁹ joules, the energy an electron gains across one volt. It is used in atomic and particle physics.
cal to eV: common questions
- How many electronvolts are in 1 calorie?
- 1 calorie (cal) is approximately equal to 2.611447 × 10¹⁹ electronvolts (eV). In short: 1 cal ≈ 2.611447 × 10¹⁹ eV.
- How do I convert calories to electronvolts?
- To convert cal to eV, multiply the value in calories by 2.6114473968 × 10¹⁹. For example, 5 cal = 1.3057237 × 10²⁰ eV.
